NAME ^

ORDB::CPANMeta - An ORLite-based ORM Database API

SYNOPSIS ^

  TO BE COMPLETED

DESCRIPTION ^

TO BE COMPLETED

METHODS ^

dsn

  my $string = Foo::Bar->dsn;

The dsn accessor returns the dbi connection string used to connect to the SQLite database as a string.

dbh

  my $handle = Foo::Bar->dbh;

To reliably prevent potential SQLite deadlocks resulting from multiple connections in a single process, each ORLite package will only ever maintain a single connection to the database.

During a transaction, this will be the same (cached) database handle.

Although in most situations you should not need a direct DBI connection handle, the dbh method provides a method for getting a direct connection in a way that is compatible with ORLite's connection management.

Please note that these connections should be short-lived, you should never hold onto a connection beyond the immediate scope.

The transaction system in ORLite is specifically designed so that code using the database should never have to know whether or not it is in a transation.

Because of this, you should never call the ->disconnect method on the database handles yourself, as the handle may be that of a currently running transaction.

Further, you should do your own transaction management on a handle provided by the <dbh> method.

In cases where there are extreme needs, and you absolutely have to violate these connection handling rules, you should create your own completely manual DBI->connect call to the database, using the connect string provided by the dsn method.

The dbh method returns a DBI::db object, or throws an exception on error.

selectall_arrayref

The selectall_arrayref method is a direct wrapper around the equivalent DBI method, but applied to the appropriate locally-provided connection or transaction.

It takes the same parameters and has the same return values and error behaviour.

selectall_hashref

The selectall_hashref method is a direct wrapper around the equivalent DBI method, but applied to the appropriate locally-provided connection or transaction.

It takes the same parameters and has the same return values and error behaviour.

selectcol_arrayref

The selectcol_arrayref method is a direct wrapper around the equivalent DBI method, but applied to the appropriate locally-provided connection or transaction.

It takes the same parameters and has the same return values and error behaviour.

selectrow_array

The selectrow_array method is a direct wrapper around the equivalent DBI method, but applied to the appropriate locally-provided connection or transaction.

It takes the same parameters and has the same return values and error behaviour.

selectrow_arrayref

The selectrow_arrayref method is a direct wrapper around the equivalent DBI method, but applied to the appropriate locally-provided connection or transaction.

It takes the same parameters and has the same return values and error behaviour.

selectrow_hashref

The selectrow_hashref method is a direct wrapper around the equivalent DBI method, but applied to the appropriate locally-provided connection or transaction.

It takes the same parameters and has the same return values and error behaviour.

prepare

The prepare method is a direct wrapper around the equivalent DBI method, but applied to the appropriate locally-provided connection or transaction

It takes the same parameters and has the same return values and error behaviour.

In general though, you should try to avoid the use of your own prepared statements if possible, although this is only a recommendation and by no means prohibited.

pragma

  # Get the user_version for the schema
  my $version = Foo::Bar->pragma('user_version');

The pragma method provides a convenient method for fetching a pragma for a datase. See the SQLite documentation for more details.

SUPPORT ^

ORDB::CPANMeta is based on ORLite 1.22 and ORLite::Mirror 1.15.
